Vodacom restricted access to my network

Can someone from Vodacom tell me when my phone will be unblacklisted and/ or my access to the network, any network at this point, will be unrestricted/ restored by Vodacom? Having spent most of the month to get my phone to work and being sent from pillar to post by Vodacom I am at my wits end. Can Vodacom do its part and ensure that I can actually use what I've paid for and not feel punished by Vodacom for moving from contract to prepaid. <br> <br> The cellphone number in question is 079****063 - this number was reactivated and converted to prepaid when I paid my account in full and terminated my cellular phone contract with Vodacom on 25 August 2015. The reactivation was completed on 07/09/2015. It then transpired that the device - iphone 5 - had been blacklisted by Vodacom. 2 attempts later the device is still blacklisted and the network is restricted. The device cannot pick up any network. The iStore confirms that Vodacom has blocked the device.
